Abstract: PURPOSE:To absorb precession when a guide plate is driven by a swash plate, by coupling a piston rod with a guide piston in a loose fit engagement, through the intermediary of slide plates having a low frictional coefficient. CONSTITUTION:A piston rod 20 at the lower end of a piston 11 is coupled with a guide piston 31 attached to a rod 14 moved up and down by a swash plate 16, at one end thereof. A piston cover 32 formed therein with a recess 33 is secured to the upper section of the guide piston 31, and a flange section 21 at the lower end of the piston rod 20 is fitted in the recess 33 through the intermediary of slide plates 34, 35 having a low friction coefficient.

Title: Formation of magnetic film layer
Inventor: NAKAYAMA MOTOHIRO
IPC: C25D7/00
Filed: 1988-04-14
Abstract: PURPOSE:To make a magnetic film layer by a method wherein Al is oxidated to provide fine holes in its surface, the amount of Fe<3+> ions in an electrolytic bath where Fe irons are mainly included is adjusted so as to control the electric precipitation of a metals mainly consisting of Fe by electrolysis. CONSTITUTION:The Al surface is oxidated and fine holes are studded on the surface. An electrolytic bath increases Fe<3+> ions so that electrolytic precipitation is suppressed. Especially the electric precipitation reaction of the fine holes is liable to be influenced by Fe<3+> ions. Then when the electric precipitation becomes hard, the Fe<3+> ions in the bath are reduced to less than 10g/l to make to surely perform the electric precipitation. When the depths of fine holes are so shallow as <5-30mum, Fe<3+> ions in the bath are controlled to 1g/l-10g/l so that electric precipitation can stably be performed with a good filling degree. Further, when the depth is so deep as 30mum or more, the Fe<3+> ions are made less than 1g/l, the electric precipitation of metals mainly consisting of Fe is promoted so as to be filled surely and densely. The ion adjustment is so performed, for instance, that an ion exchange film 15 is used so as to regulate the amount of Fe<3+> ions in the bath by electrolysis and simultaneously to supply the Fe<2+> ions to be consumed.

Abstract: PROBLEM TO BE SOLVED: To make the movement in an axial direction possible, by comprising a fixing means for fixing a shaft and a bearing together relating to the rotation of the shaft and the bearing. SOLUTION: In a normal operation, the translation of a cylindrical part 30 of a shaft 10 is guided by a bearing surface 54 of a bearing 14, the shaft 10 is not kept into contact with the bearing surface 54 on a flat part 34, and, on the other hand, a flat face of a projection 58 is slid along the flat face of the bearing surface 54, and does not inhibit the sliding of the shaft 10. When the shaft 10 is moved relatively to a sheath 12, the torque is transmitted through an arm of a spider 44 holding a roller which rolls along the inside of a groove 42. When the rotation of the shaft 10 is suddenly stopped by the failure, the sufficient force is generated on the shaft 10 and the sheath 12, and the shaft 10 breaks a peripheral groove 20 by the shear force. Accordingly the rotation connection means 18 of the shaft 10 and the sheath 12 is released.
